WuXi Biologics
Offering End-to-End Solutions
At WuXi XDC, we leverage in-house expertise and state-of-the-art analytical equipment to characterize the distinct intermediates (e.g., protein/mAb, payload and linker) and the bioconjugate including antibody drug conjugate (ADC) therapeutic candidates or diagnostic and imaging reagents at various stages of development. Methods utilized to assess and characterize these complex bioconjugated molecules include UV/VIS, HPLC, cIEF, LC-MS amongst others as is analytical assessment of drug-to-antibody ratio, free-drug content, ADC affinity, protein concentration, aggregation, PI, and peptide mapping. Methods utilized to assess and characterize these complex bioconjugated molecules include (but are not limited to):

Formulation and Drug Product Development
We offer extensive end-to-end services for formulation/process development for a wide variety of bioconjugates. Our team assists from early-stage molecular assessments to development of First-in-Human (FIH) formulations to enable clinical trial starts. Additionally, we further provide commercial formulations lock and process/device development in preparation for product launches.
We are experts in developing liquid, frozen or lyophilized dosage forms filled into vials as well as special dosage forms for products containing nanoparticles and other advanced molecular complexes.
Our services include, but are not limited to:
